Wireless

The Huygens Laboratory and Oort Building have been configured with a wireless network that is both University Generic and HL/Oort specific. The current wireless access points should cover most of the building space and you should be able to see a number of wireless networks everywhere.

These wireless networks have the following names:

Leiden University

Eduroam

UL-STRW-LION

nuwd-laptop

Each of these networks have their own specialities. Lets discuss below what they are for each network and how to connect to it. All of the networks (except UL-STRW-LION) are university wide networks available everywhere at each of the university buildings.The UL-STRW-LION networks are available only in the Huygens Laboratory and Oort Building and give special access to LION and STRW resources such as printers and shares.

NOTE: If you want to make use of the special facilities provided by the UL-STRW-LION do NOT login to the Leiden University network. That will block your MAC-address and disable login to UL-STRW-LION. If this has happened (by accident) then request your MAC-address release from the ISSC (mail to helpdesk@issc.leidenuniv.nl).
